Back by popular demand, the SIM-only deal sees customers receive entirely unlimited data as well as unlimited calls and minutes.

Other add-ons include 'Personal Hotspot' which allows you to connect to your unlimited data from another device; 'Go Roam Around The World' which allows you to use your data without any extra charges in 71 destinations around the world and 'Go Binge' which allows you to stream TV, movies and music without any further charges.

To date, Netflix, Deezer, Soundcloud and TV Player - which enables access to Freeview channels - are all on 'Go Binge'. You can see the SIM here.

After 12 months, the contract should cost you a total amount of £240. However, there is one way shoppers can save even more.

The Deals

Combining the unlimited SIM offer with a cashback deal could save an extra £70 immediately. Deals website Quidco is offering £70 cashback on the Three SIM deal, meaning you will get £70 for signing up.
